Champions League Quarter-final Advancement Probability: Arsenal Highest at 77.7%, Bayern 64.5%, Real Madrid Underestimated

The Champions League is the highest-level club competition, and the trophy is the gateway for European clubs to join the elite. The first legs of the 2025-26 Champions League quarter-finals will kick off this midweek, with eight teams competing for four semi-final spots, includingSporting vs Arsenal, Real Madrid vs Bayern, Barcelona vs Atlético Madrid, Paris vs Liverpool.

Opta has predicted the semi-finalists for this season's Champions League based on factors such as squad strength and recent form. Arsenal's advancement probability is the highest at 77.7%, leading the eight teams; followed by Bayern at 64.5%, while Real Madrid is once again underestimated at only 35.5%; Barcelona ranks third at 68%, and Paris fourth at 59.6%.

This means Opta favors Arsenal to eliminate Sporting, Bayern to eliminate Real Madrid, Barcelona to eliminate Atlético Madrid, and Paris to eliminate Liverpool to advance. Sporting, Real Madrid, Atlético Madrid, and Liverpool are the four teams considered less likely to advance. So the question is: are Opta's predicted Champions League semi-finalists the same as your ideal answer?

Some fans commented: Barcelona's probability is too low; Barcelona historically dominates Atlético. Bayern's is too high; Real Madrid has various "mystique" in the Champions League, and their double victory over Manchester City this season with a depleted squad is the best proof. Whether it's Bayern's triumph or Madrid's upset is still uncertain! Arsenal and Paris advancing should be relatively assured.
